Application fi1ed Ju1y 23, 1910. Serial No. 573,334.

To all whom it 722 try concern: Be it known that I, ADELBICRT V. DAN- IELS, a citizen of the United States ofi America, residing at. Morrison, in the county of \Vhitcside and State of Illinois, have invented'new and useful Improvements in Corn-Flows, of which the following. is a specification.

This invention relates to corn plows or cultivators, and it has for its object to provide a device of this class which shall pos superior advantages in point of simplicity, durability and general etiicieiicy.

. 1th these and other ends in view which will readily appear the nature of'the iiivention is better understood, the same consists in the improved construction and novel arrangement and combination' of parts which .will be hereinafter 'fully described and particularly,pointed out 'in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that. no limitation is necessarily made to the precise structural details therein exhibited,

,but that changes, alterations and modificatio'ns within the scope of the claim may be resorted to when desired. i

In the 'drawings,Figure 1 is a top plan view, showing a cultivator gang and aportion of the-axle or. frame upon which it is mounted. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation. a. side view of one of the disk carrying shanks showing the disk in position. Fig. 5

is a seetionaldetail view taken on the li'i'ie in Fig. 4., Fig. 6 is a perspective detail view of one of the blocks carrying the springs whereby the disks are retained in position.

Corresponding parts in the several fig":-

ures are denoted by like characters of reference.

The cultivator gang includes two parallel beams 1, 1 constructed preferably, of tubular iron, each being provided adjacent to 7 its front end with a sleeve 2 having a forat .its oke 8.

wardlyextending lug 3. A sleeve i mounted revolubly upon the axle or frame bar. '5 is provided with rearwardly extending lugs (lwith which the lugs 2 are pivotally connected. Each-of the beams is provided t. designates the framejco iposed' of top Fig. .4 is

rear end with a sleeve 7 carrying a and bottom bars 9 and 10, each oiiwhich is 9, 10". The uppcif'and lower frame bars are terminallyconnected by vertical side bars 11. lhe"tranie is secured between the side members of the yokes 8, 8, saidframe being thus maintained in a vertical posit on. The frame A is provided adjacent to the ends thereof with boxes or bearings 3 12 for the. shanks 133 which are secured by set screws 12. The lower ends of the shanks are bent to form disk (airrying spindles- 1-1. The disks 15 are provided with hearing members 1'6 which are in the naturc of sockets, firmly bolted or otherwise secured upon the concave taccsof the disks, and adapted to be mounted for rotation upon the spindies 14:. The disks aren-ctained upon the spindles or bearings by means of springs 17 which are secured upon sleevc's 18 mounted upon the shanks 13 where said sleeves may be secured adjustably by means of set screws 25 or lll'itlly other convenient inaiu'ier. Each of said sleeves is provided wilhla hat inclined face, best seen at 19 in lfig'. (3, upon which the spring 17 is pivotally secured by a fastening member, such as a rivet or screw 26. Each of said -slee\ 'es is also provided adjacent to its forward edge avith a flange 20'lying in the path of the spring 17 andserving to sustain said spring normally in an upright position and to prevent it il'Olll turning in aforward direction upon the rivet or pivot whereby it is securedin position. The lower ends of the'springrs constitute disk retaining scrapers which by engaging the concave faces of the disks serve to free the latter from adhering dirt, said sy irings being also made of sullicicnt strength to retain the disks securely upon the spin -dles when 'the device is in operation. When it shall be desired to remove the disks from the spindles,-this,inay be readily accomplishedxby throwing; or moving the lower ends of the-springs rearwardly to the position indicated in dotted lines in Fig. 4, thus moving the engaging pOrtiQnsof the springs out. of the path of the disks. The upper endso't the springs are preferably round, as shown at 27, to enable them to be conveniently moved in the manner indicated.

The. name A may be provided with'beari'ngs 21 having a shank 22 carrying an ordinary cultivator blade 23, said blade being used intermediate the disks when desired. A handle 23 is suitably connected with the frame A, as shown.- a

From the foregoing description, taken in connection with the drawings hereto anneXed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. It will be seen that by means of the handle 23 the cultivator gang may be moved laterally to the position indicated in dotted lines in Fig. 1' without varying the distance between the disks or earth engaging implements and Without changing the angle at which the said earth engaging implements are presented, the frame A maintaining a parallel relation to the sleeve 4. The advantage of this will be obvious to tillers of the soil, because the efliciency of the earth engaging im'plements 1s unimpaired no matter what adjustment may be necessary with ref-' 'erence to the row of plants that is being operated upon. The construction is simple and inexpensive, and the disks may be readily adjusted atany desired pitch, and

, they may be conveniently adjusted so as to throw the dirt in the desired direction'either toward or from the row of plants thatvis being operated upon. The disks may be very readily removed for sharpening or other purposes without the use of tools and Without the necessity of specially skilled labor, and the device is thoroughly efiicient for the purposes for which it is provided.

Having thus described the invention, what is claimed as new, is:-

In a cultivator, an implement carrying y at oneend and rearwardly at theother end and provided wlth bearings adjacent to the ends-thereof, verti-' cally disposed implement carrying shanks mounted rotatably and vertically adjustable in said bearings, means for securing the.

shanks in adjusted position, parallel beams having vertically disposed yokes at their rear ends, the limbs of said yokes being pivotally connected, respectively, with the top and the bottom member of the, implement carrying frame, and a draft member with which the front ends of the parallel beams are pivotally connected.

In testimony whereof I afiix in presence of two'witnesses.
